NHTSA Complaint #11513767 — 2014 KIA SORENTO

Hi, I'm dealing with my Kia Sorento SX 2014, rpm and acceleration problems, for over two long years, sometimes shut off itself, some times codes shows up but no all the time, already changed spark plugs, High pressure fuel pump and the connector, two injectors, starter, MAP sensor, etc. My mechanic tell me today that I need to change the wiring harness, so everything is just guessing and spending crazy money, also the dealer don't know the exactly is the problem, already two years with this frustration and still don't know what to do, please I really need a very professional advice in this incredible situation, some of the codes that shows up, if I'm lucky are: P0087, P0506, P2096, P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0133, P0137 and so... but right now all of these disappeared, I read in the NHTSA web site about the problems with engine and electric components reported with this car in this specific year and I'm really worry about my family and my safety while I'm driving this vehicle, please, please, please... I already went to many different mechanic experts (Including the Kia dealership) and still nobody knows what's producing this lack of acceleration in the engine at the time of starting and its subsequent shutdown.
